UNITED STATES PATENT OFFICE.

SAMUEL HEA'ION, OF KINGSTON, IO'WA.

IMPROVED SCRGHUM-EVAPORATOR.

Specification forming part of Letters Patent No. 48,397, dated June 27, 1865.

To all whom it @nay concer-n:

Be it known that I, SAMUEL HEATON, of Kingston city, in the county of' Linn and State of'Iowa, have invented a new and` useful Improvem ent in Sorghum-E vaporators and I do lhereby declare that the following is a full, clear,

The letterA represents a furnace, over which the juice or sap is boiled. B is the pau that holds the juice or sap. C G are upright arms,

attached to the pan at their lower ends and to a cross-bar at their upper ends D is a crossbar resting on two levers. E E areltwo levers, upon which the crossbar rests. They are fastened at one end to a post or other fixture by Vbolts f j', upon which they may be'turned so as to allow their opposite ends to be raised or lowered'atm'ill. The ends of these levers are raised or lowered at will in 'grooves or niches formed for that purpose on the sides of upright posts, and are held inposition when raised by means of the hooks gg, or they may rest on the lowerendsof the grooves or niches in the posts.

4In one corner of the pan B, I place a plug, representedby z', for the purpose o f drawing oft' the contents yof the pan.

I may make ,both ends of the cross-bar D where it rests upon the levers either flat or round, but I prefer to have one end Hat and the other round, as represented iu the drawings.

The mode of operating my apparatus is as follows: I place both levers down or oft' from the hooks y g, by which movement the pan is lowered to the top of the furnace and rests upon it, closing the upper face of the same and cre- I then fill the panwith juice or sap, and boil it down to Sirup. To remqve the pan from the lire, I raise the frontend of both levers and fasten them upon the hooks g g. I next slide the cross-bar D on the levers tow-ard the front posts until I have removed the pan as far from the tire as may be desirable. 'Ilo remove the contents of the pau 'when the same is boiled down to sirup or sugar, I drop that lever from the hook which is on the same end of the pan as the plug, and let it rest on the lower end of the niche or groove. By this movement the contents ow to that end of the pan in which the plug is placed, and are easily drawn on. When the pan is emptied I replace the plug and restore the-lever toits place upon the hook. I then slide the'cross-bar to .its position above the furnace, rell the pan with juice, and proceed as before stated.

The advantage of my invention is that by means thereof one person can easily and almost instantly remove a large pan from the furnace by raising the front ends ofthe levers aud placing them ou the hooks, thereby lessening in a great measure thel losses incurred by boiling over and -buruing so common to all other apparatus heretofore used.

By means of my invention one man can easily remove a pan from the furnace that is ten feet iu lengthv and two-and-a-half feet in width, and filled with juice, without danger of spilling the contents or of injuring the furnace by dragging dow u its sides. The pau becomes easily movable, while at the same time it is made to sit closely on the furnace, if desired, with all the advantages of a fixture thereto.

By means of the levers the pan can be kept at just that distance from the fire the operator may choose, and any degree of heat secured thereby which he may consider best for his purposes.

What I claim as new, o'f my invention, and desire to secure by Letters Patent, is-

l. The levers E E, constructed in the manner and for the purposes specified, substantially as set forth.

2. The cross-bar D, constructed in the manner and for vthe purposes specified, substantially as described.

3. The swinging-hooks g g, constructed in the manner and for the purposes specified, substantially as described.

4.' In combination with an evaporator, the levers E E, the cross-bar D, and the hooksg g, constructed and operated substantial] y as and for the purposes herein specied.
